dear Ritu Singh learn your history first. The native Tamilians have been in Sri Lanka for thousands of years, they may have absorbed Chola and Pandyan Tamilo ivaders and immigratns in to their community and so did the Sinhalas. The Tamils haveb been ruling ther territories as seperate kingdoms and chiefdoms. And the Sinhalese theirs. ( althoug many of these so called Sinhala and Tamil kings were actually Tamil). It was teh British woh united the Tamil and Sinhala parts of Sri Lanka in to one country in 1833 and caused the problem. The SInhalas race origin also started when Prakrit speaking migransts from North Indian came to Sri Lanka around 2500 years ago. These Immigratns did not bring their woman folk, do therefore they took local andPandyan Tamil women as their wives. They also intermingled with the local Veddhas, Yakkas and Nagas. This and the intrdoduction of Buddhism changed the language from Tamil to the newly evloving language which was a mixture of Pali/Tamil and Sanskrit. Modern Sinhala has around 35 to 40% Tamil root words and its sentence and grammatical structure is Tamil. The population in the North and East of Sri Lanka remained Hindu so they reamined Tamil too. Infact the ancesntors of around 50% of the present day Sinhalas only migrated around 600 to 100 years ago form southern Tamil Nadu /Kerala( when Kerala was Tamil speaking) . So get you r fact coorect beofore commenting yuo biased north Indian. The Eealm Tamils are as native as the Sinhalas.
